Hi,
There are two steps you need to perform.
1. Uploading the lookup file
First you have to create the .csv where you need to fill the IP address in first column and name would be in the another column.
Go to lookups ->Lookup table files >> New lookup file
Give the name of the lookup filename. this name will be lookup name for splunk. filename should end with .csv
Creating automatic lookup:
Once you are done with uploading the file. Next step is create automatic lookup.
Go to lookups ->Automatic lookups >> New Automatic lookup
Select the destination app and fill the name whichever you want.
You have to select the lookup table which you have given previously(lookup filename)
Give the source type which you want to apply this lookup
Now, you have to fill the input and output field.
In your example , IP address will be the input field and Name will be the output field.
IPAddress = IPAddress
Name=Name
Click save.
If you search with the sourcetype, you will get the new field with "Name"
Please let me know for any challenges.
